Abstract

OBJECTIVE : The objective of this study was to profile speaking F0 and its variations in newsreaders on varied emotional texts.
METHODS : This study has a prospective, case-control study design.
METHODS : Fifteen professional newsreaders and 15 non-newsreaders were the participants. The participants read the news bulletin that conveyed different emotions (shock, neutral, happy, and sad) in a habitual and "newsreading" voice. Speaking fundamental frequency (SFF) and F0 variations were extracted from 1620 tokens using Praat software (version 5.2.32) on the opening lines, headlines, news stories, and closing lines of each news item. Paired t test, independent t test, and Friedman test were used for statistical analysis.
RESULTS : Both male and female newsreaders had significantly (P ≤ 0.05) higher SFFs and standard deviations (SDs) of SFF in newsreading voice than speaking voice. Female non-newsreaders demonstrated significantly higher SFF and SD of SFF in newsreading voice, whereas no significant differences were noticed in the frequency parameters for male non-newsreaders. No significant difference was noted in the frequency parameters of speaking and newsreading voice between male newsreaders and male non-newsreaders. A significant difference in the SD of SFF was noticed between female newsreaders and female non-newsreaders in newsreading voice. Female newsreaders had a higher frequency range in both speaking voice and newsreading voice when compared with non-newsreaders.
CONCLUSIONS : F0 characteristics and frequency range determine the amount of frequency changes exercised by newsreaders while reading bulletins. This information is highly pedagogic for training voices in this profession.
